Each group will form a circle and all they have to do is to
analyse the picture and use a mathematical equation
which is the + and - .to answer the clueless word. Each
group will answer the hidden word using a pen and bond
paper. Whoever group will have the highest score will be
the winner.

Objectives:
1.Describe volcano and it’s parts.
2.Illustrate and describe the different types of volcano.
3. Infer the importance of knowing the different types
of volcano.

Picture Perfect

14.
Volcano
A Volcano is an opening in the Earth’s
crust through which lava, volcanic ash,
and gases escape.

15.
Parts of a Volcano

16.
Crater
Is the mouth of a
volcano and can be
found at the top of the
volcano

17.
Craters- are formed by the outward explosion of rocks
and others materials from volcano. They are usually more
circular than calderas and usually much smaller than calderas.
Caldera- are formed by
the inward collapse of a
volcano during or after an
eruption.

18.
Main Vent
A point in the Earth’s
crust where hot magma
has been able to rise
from the magma
chamber and reach the
surface.

19.
Magma
Chamber
Large underground pool
of molten rock sitting
underneath the Earth’s
crust.

20.
Lava
Magma
Magma- a molten rock
beneath the Earth’s crust
Lava- a molten rock that
reaches the Earth’s surface
during volcanic eruption.
Ash- is a mixture of rock,
mineral, and glass particles
expelled from a volcano during
a volcanic eruption.

Standards in Doing Group Activity
1. Read the instructions carefully.
2. Work quietly and cooperatively.
3. Observe time management and
cleanliness.

22.
Activity 1: I am Who Say I
am
Group 1
Based on the picture you have, describe the
Composite Volcano using “Concept Map”
Group 2
Based on the picture you have, describe the
Cinder Cone Volcano using “Volcanic
diagram”
Group 3
Based on the picture you have, describe
the Shield Volcano using “Mind Mapping”

23.
Types of a Volcano
Composite Volcano or Stratovolcano
Large, nearly perfect sloped structures
formed alternate solidification of both
lava and pyroclastic deposits.

24.
Cinder Cone Volcano
• The simplest and most common type
of volcano.
• This is built from ejected lava
fragments. They have a steep slope,
wide circular crater.
Mt. Paricutin
in Mexico

25.
Shield Volcano
• Very big in size, formed by the
accumulation of lava that oozes out
from the volcano. Since non-viscous
lava can flow freely. A broad, slightly
doomed structure that resembles a
warrior’s shield is formed.
Mauna Loa
in Hawaii
